Matt is super nice, very professional, very knowledgeable and has been doing it for a very long time. He and his crew did a fantastic job on our garage attic installation job. Definitely feel a difference in temperature. Well worth the money spent.

Read the Google Reviews and decided to approach West County Insulation for my historic home re-insulation after water and mold damage. They did a phenomenal job talking options with me for eco-friendly and something that would allow the home to breath appropriately. Could not beat the price and level of service and professionalism. Used them for cellulose batting and blow-in for the attic spaces beyond the bedroom walls. Cannot recommend them enough.
I am so glad I contacted West County Insulation for a second opinion. Brandon S had great communication, so friendly (but not tooo friendly). Super professional, intelligent. Was he a sales person? Felt like he was just there to take photos and explain how to make my attic insulation more effective. I'm hiring the company to redo my insulation (just had to come on here and rave about the sales rep!) I'll update the review if the labor is not fittingly excellent
West County insulation did an incredible job with removing and replacing our attic insulation! They quickly got us competitive a quote and Brandon was excellent explaining the process and working with us to reschedule installation when our electrical work took longer than expected. David and Isaac performed the insulation removal and installation: both were kind, informative, and left the area around our attic and stairs cleaner than when they came! Highly recommend this company for any insulation needs.

I-foam did a great job on my shop! The fellas that showed up were professional and were done in no time. I will definitely be using them for future projects.
I was extremely pleased with this whole process. From Scott and his team coming out to give the bid to the two gentlemen that came out to do the install of my insulation. Very professional and worked very quickly. Paid very close attention to detail and explained steps as they went. You will not be dissatisfied at all if you choose this company. They were also very affordable. Thank you Scott and your entire team for such a great job. I will make sure that I share my experience with friends.
They were able to do blown in insulation in my basement finish for the same price as the material costs for rockwool insulation. They were great during scheduling and completed the work very quickly. 10/10 wood recommend!

My husband and I had a great experience with Koala Insulation. They showed up on time for our appointment, charged us a great price, and were in and out in about an hour for the actual service. They even cleaned up like they were never there! Wish all businesses were so easy to work with. Highly recommend!
its always great when someone does such a stellar job and everything goes smoothly, definitely a big relief. Brianna was amazing through out whole insulation press she really made it difference when everything streamlined and well coordinated. great company wonderful staff.
Koala give a free assessment. In the quoting process they go over every aspect of the attic space and what it needs and nice to haves. They gave me a few different options in the quote to best suite my budget and what I wanted. The work was done about a week ago at time of this review. I think it will be hard to quantify the effect right of way adding insulation to the attic, but it is supposed to help keep hot air out of the house in the summer and keeping the heat in in the winter. I am pleased with how professional both the quoting person and the install crew were.

I cannot say how great these people are. It was a last minute Schedule to get done They were able to work around the last Minute request. I had to get my sighting replace. I've been waiting for a year and they finally said we're here to do it, so that was the perfect time when everything was off to get it insulated. Thank you so much for the hard work.I noticed it as soon as I get Home.The back bedroom was 5 to 10 degrees cooler
Foam Co. was very easy to work with. We had new insulation blown and sprayed in. They were able to get it done in a day and went above and beyond providing pictures of the install and working independently. They communicated promptly and clearly throughout the process.
Very professional company from the beginning of the project to it's completion. Every person was nice and respectful. When they say the workers will start at 7am that is what they ment. They blew in our new insulation. They came right in, introduced themselves and got to work. The project did not take long at all and they cleaned up behind themselves. The price for the job was nice too. If we need any more work done we will be calling them again . James and Brenda Lee

Mindy, came and explained the process… The guys who installed were fast and left no cellulose mess behind… the price was affordable! Can’t be happier with Foam Engineers and their staff.. referred them to my neighbor who’s getting her attic done too!
Foam Engineers has exceeded my expectations. I’m a project manager for a home renovation company and have worked with Foam Engineers on my last two projects. Their pricing is very competitive, and their service is outstanding. Dave and his crew installed both spray foam and batt insulation on my most recent project. They were prompt, professional, and maintained excellent communication throughout the process. They went above and beyond in both scope and execution. I’ll continue to use Foam Engineers for future projects and have already recommended them to my colleagues.
Very impressed from start to finish with Foam Engineers! Mindy came out for the estimate and was extremely thorough in explaining the process of installing cellulose insulation and the resulting benefits. The estimate was very detailed, including photos.The installation took place yesterday and we had a fabulous crew! Alex was the lead and impressed me with his knowledge and professionalism. Colin, Dylan, and Tony were all very competent and skilled workers as well. All were committed to the successful completion of the project in a timely manner. I had to run an errand and felt comfortable leaving the guys on their own. Mindy dropped by during the installation. Her attentiveness and follow-up were very much appreciated. I wouldn't look further than Foam Engineers for your insulation needs. Bravo to Mindy and the crew of four - thank you for a job well done!

This is the third home I've had done by Aladdin and it was wonderful as usual. They put an additional amount of insulation in the attic and brought it to r49. They added insulation to the garage. They also spray close cell phone insulation on the sill plate in the basement in my house I can already tell seems to be warmer. Another wonderful job!
This is a trucker review: Super nice people! I arrived during the night. Gentleman knocked on my door and said "as soon as you're ready I can get you unloaded". It's a small area but they left spots open so it's easy to maneuver. Offered me coffee, bathroom, water, or if I needed anything else. Hope I get to deliver here again.
From the estimate to service look no further ! Honest and hard working crew. Jason and Brad made sure my attic looks like a Winter Wonderland.
